Gibson 2017 GMC Sierra 1500 Base 5.3L 3in/2in Cat-Back Super Truck Exhaust - Stainless

This Gibson Super Truck cat-back exhaust system is built for your 2014-2018 Chevrolet Silverado 1500 with the 5.3L engine. It's designed to give your truck a serious performance upgrade, starting with a loud, deep, and powerful sound that exits through dual tailpipes positioned in front of the rear wheels, each capped with a stainless steel tip. You can expect a noticeable rumble and improved acceleration, with manufacturer dyno tests showing average gains of 15-18 horsepower and 15-20 lb-ft of torque.

The system features 3-inch diameter tubing that steps down to 2-inch for the tailpipes, all made from durable stainless steel with mandrel bends to ensure smooth airflow. The Superflow muffler uses a baffled and chambered design without internal packing, contributing to its aggressive sound profile while minimizing interior drone. Installation is straightforward thanks to its bolt-on design, meaning no welding is required, and it comes with a lifetime limited warranty for peace of mind. Keep in mind this system is not recommended for towing and may produce sound levels exceeding 95 decibels.
